"Diving" is the word he used, and since the plane certainly lost altitude between hitting the top of the lightpoles on the bridge and hitting the base of the building (and since it couldn't get between those two points with a "level approach"), I think his description is more accurate than yours.
The "friend" is a "neighbor" of my "parents." What are you trying to imply with the quotes?
Yes, he's anonymous -- to you -- and shall remain so. He seemed pretty sincere when he said you guys are "full of $#!%" so I don't think he wants to be "interviewed" by the "citizens investigation team."
No, I can't prove he was on that highway or saw what the says he saw, but I have absolutely no reason to doubt him since his story is completely consistent with all the other witnesses and all the physical evidence. The "north side flight path" is irrelevant, since for our purposes here the important part of his story is what he didn't see: a flyover. If you choose to disbelieve him just because it makes your idiotic theory harder to sell, suit yourself. But I'd still like to hear some rational explanation for how anyone from that vantage point could have possibly missed seeing a 757 fly over the roof in my photo or mistook it for a plane on a National flight path. You previous attempt at that was, um, somewhat less than credible.
Ah OK. Anonymous hearsay=i.e. your witness does not exist.
Ok, next.
